Miscellaneous: key points

This set covers computer fundamentals: memory units, number systems, the generations of computers and basic software terms.

  • 1 byte = 8 bits and 1 kilobyte = 1024 bytes.
  • Generations: vacuum tubes, transistors, integrated circuits, microprocessors.
  • RAM is volatile and loses its contents without power; ROM does not.
  • A compiler translates the whole program at once; an interpreter translates it line by line.
